A non-sterile inflatable device in the form of a stocking, sleeve, or suit intended to be applied to the limbs externally to promote venous blood flow. As part of a compression system, the device applies pressure to the extremities through the sequential inflation of several chambers. The resulting increased venous blood flow may help to treat/prevent oedema, deep vein thrombosis (DVT) and pulmonary embolism (PE) in non-ambulatory patients or patients at risk. This is a previously used single-use device that has been processed for an additional single-use patient application.
